ROLLER-BEARING.

SPECIFICATION forming part of Letters Patent No. 790,712, dated May 23,1905.

Application filed August 23, 1904. Serial No. 221,851.

To all whom it may concern.-

Be it known that I, ROBERT FRANKLIN BOWER, a citizen of the UnitedStates, residing at Lima, in the county of Allen and State of Ohio, haveinvented anew and useful Improvement in Roller-Bearings, of which thefollowing is a specification.

My invention is an improvement in rollerbearings, and especially in suchbearings designed for use on vehicle-wheels; and the invention consistsin certain novel constructions and combinations of parts, as Will behereinafter described and claimed.

1n the drawings, Figure l is a longitudinal section of a portion of avehicle-hub provided with my improvements. Fig. 2 is a crosssection onabout line 2 2 of Fig. 1, and Fig. 3 is a detail side view of one oftherollers.

In the accompanying illustration I have presented the axle A with itsspindle B, having the shoulder C at its inner end and its outer endthreaded at D to receive the nut E, as is usual. The spindle B may bethe ordinary spindle, and on it is fitted the inner cone F, bearing atits inner end against the shoulder C, grooved in its outer face at f forthe flange of the inner rollers and having at its outer end the tubularextension F", which is threaded to receive the outer cone G, which isgrooved in its outer face at g to receive the flanges of the outer setof rollers and is arranged at its outer end to be pressed against by thenut E, screwed on the stem D and serving not only as a jam-nut for thecone G, but also as a means for clamping the cone.F against the shoulderG, and so holding it from turning on the spindle without necessitatingthe provision of keys and keyways, as might otherwise be necessary.

The outer casing consists of the sections H and I, which telescope attheir inner ends one in the other and slide into the opposite ends ofthe hub, which is bored out to receive them. The sections H and l havecone portions corresponding to the cones F and Gr, are grooved at it andopposite the grooves f and g, and are rabbeted in theirouter ends andthreaded at h and t" for the inner and outer race-rings J and K, and aregrooved at 71,2 and 2' to receive the end balls L on the rollers L, the

rings J and K being also grooved at J and K to receive said balls. asshown in Fig. 1. The rollers are also provided with flanges L to operatein the grooves in the cones and casing-sections.

In operation the end balls L, operating in the raceways provided by thegrooves before described, prevent the rollers from getting out ofalinement When one roller is smaller than another.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The improvement in roller-bearings herein described comprising thecombination of the spindle having a shoulder at its inner end and athreaded tenon at its outer end, the inner and outer cones littedtogether and on the spindle, the n ut on the spindle-tenon and bearingagainst the outer cone and clamping the cones upon the spindle, saidcones having an- I nular grooves in their outer faces, thecasingsections fitting together over the cones and provided in theirinner faces with grooves opposite those in the cones and having at theirends the grooves for end balls on the rollers and threads for therace-rings, the race-rings engaging said threads and grooved for theroller-balls and the rollers having end balls whose diameters aregreater than the diameters of the rollers immediately adjacent to saidend balls, the latter being arranged and operating in the grooves in therace-rings and casing-sections and each of said balls being in contactwith the adjacent balls whereby to prevent the rollers from getting outof alinement substantially as set forth.

The combination in a roller-bearing of the cone-sections, thecasing-sections and the rollers provided at their ends with balls rigidwith the rollers the diameters of the said end balls being greater thanthe diameters of the rollers immediately adjacent to said balls wherebyinwardly-facing rounded shoulders are provided facing toward theopposite or inner ends of the rollers each of said balls being incontact with the adjacent balls substantially as set forth.

3. A roller-bearing comprising the combination with the cone-sectionsand the rollers ing-sections grooved in their opposing surfaces, and therollers having the intermediate flanges operating in said grooves andthe .end balls the diameters of the balls being greater 5 than thediameters immediately adjacent to said balls and a race-ring receivingsaid end balls and holding the same in contact with each othersubstantially as set forth.

ROBERT FRANKLIN BOWER.
